A whole-body serial electron microscopy volume of a three-segment Platynereis dumerilii larva gives over 1,500 reconstructed neurons, 6,500 non-neuronal cells, 180 neuronal types and traced sensory-to-effector pathways.

The paper identifies anatomical subtypes of dopaminergic neurons in Drosophila and their specific input connectivity, revealing functional roles in reinforcement and memory.
